Description

Technical Field

[0001] This invention relates to the interdisciplinary field of product lifecycle management and process-oriented manufacturing process design, and in particular to a visualization design method and system for tire formulation application based on Teamcenter. Background Technology

[0002] With the advancement of digital transformation in the manufacturing industry, Product Lifecycle Management (PLM) systems have been widely applied to product data management and process collaboration. In process-oriented manufacturing industries such as tires, formulation design is a key link connecting formulation development and production execution. Its core tasks include automated calculation of material usage, structured modeling of process steps, and full lifecycle management of formulation data.

[0003] Currently, tire manufacturers mostly use spreadsheet-based macro calculation tools or independent database systems to assist in completing tire formulation design. For example, some companies use Excel VBA macros to calculate the amount of basic materials, but the splitting of fine materials into bags still requires manual allocation based on the smallest packaging unit; process steps are recorded in tabular form, and changes to process parameters require modification row by row, making it difficult to intuitively express the serial / parallel logical relationships between processes. Patent document CN112699114A discloses a method and system for processing tire formulation data, which achieves centralized storage and version control of formulation data based on a relational database. However, this solution focuses on static formulation data management and does not involve dynamic calculation and visual process editing functions for the construction process, nor can it achieve deep integration with the business processes of a PLM system.

[0004] The aforementioned existing technical solutions have the following technical defects: (1) The calculation of formula parameters lacks a constraint-driven automated mechanism. The material usage calculation process is disconnected from physical constraints such as equipment capacity and minimum packaging unit. The fine material splitting relies on manual trial calculation and experience adjustment, making it difficult to verify abnormal states such as overweight or imbalance in proportion in real time. The calculation results have low reliability and are difficult to trace.

[0005] (2) The process step modeling lacks structured and visual representation capabilities. The process flow is stored in static table or text form, which cannot intuitively present the logical relationship and parameter dependency between processes. When the process changes, the associated parameters need to be modified manually one by one. There is a lack of parameter linkage update and automatic logical conflict verification mechanism, which makes it difficult to support the rapid iteration and optimization of process solutions.

[0006] (3) There is a lack of a unified lifecycle management model for formula data. Process parameters are stored in heterogeneous systems, and the integration with the PLM platform is limited to the data storage level. Business operations such as formula calculation and process editing are not embedded into the PLM workflow, resulting in the phenomenon of "data entering the database but business going offline", which leads to inconsistencies between design data and production execution data.

[0007] Therefore, there is an urgent need for a formulation construction design method that can achieve constraint-driven automated calculation, structured and visualized process modeling, and deep integration with the product lifecycle management system. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology. To achieve the above objectives, a Teamcenter-based visualization design method and system for tire formulation construction is adopted to solve the problems mentioned in the background technology.

[0009] The first technical solution: a visual design method for tire compound application based on Teamcenter, comprising the following steps: Receive construction design instructions for the formulation object, and obtain bill of materials data and manufacturing resource data from the product lifecycle management system; Based on the bill of materials data, identify the sub-materials that need to be split, and generate a material bag splitting scheme according to equipment capacity constraints and preset rules; In response to the user's editing of the material bag splitting scheme, update the splitting scheme and generate semi-finished product objects of the associated fine materials; Based on the manufacturing resource data, a process configuration interface corresponding to the machine tool is dynamically generated. In response to the user's input of processes and parameters, a mapping algorithm is executed to generate a sequence of process steps with parameters. The process step sequence is associated with the semi-finished product object to generate a construction standard object, and a versioned association is established with the formula object.

[0010] As a further aspect of the present invention: the identification of sub-materials to be split based on the bill of materials data specifically includes: Iterate through the material entries in the bill of materials data, obtain the classification attribute associated with each material entry, and when the weighing method attribute value in the classification attribute matches the preset fine material scale identifier, classify the material entry into the fine material set.

[0011] As a further aspect of the present invention: the step of generating a bag splitting scheme based on equipment capacity constraints and preset rules specifically includes: Obtain the total weight of each material in the fine material set; The total weight is compared with at least one weight threshold. When the total weight is greater than or equal to the first threshold, the number of material bags is determined to be the first quantity; When the total weight is less than the first threshold and greater than or equal to the second threshold, the number of material bags is determined to be the second number; When the total weight is less than the second threshold, the number of bags is determined to be the third number; The total weight is evenly distributed among the bags based on the determined number of bags.

[0012] As a further aspect of the present invention: the method for splitting the material bag further includes: Based on the compatibility relationship between each batching machine and the processable materials defined in the manufacturing resource data, the matching degree between the materials in the fine material set and each batching machine is calculated. The batching machines are sorted according to the matching degree, and the materials in the fine material set are automatically allocated to the material bags associated with the corresponding machines according to the sorting priority. Materials not assigned to any batching machine are placed in the semi-automatic weighing area.

[0013] As a further aspect of the present invention: the semi-finished product object for generating related fine materials specifically includes: Create a semi-finished object for each split bag; In the bill of materials structure of the semi-finished product object, add material entries belonging to the bag, and set the usage, weight and bag serial number attributes for each material entry.

[0014] As a further aspect of the present invention, it also includes: After updating the bag splitting scheme in response to a user's editing operation, the consistency of the bag splitting scheme before and after the update is verified. Version upgrade operations are performed on the corresponding semi-finished objects only when the content consistency verification result is changed.

[0015] As a further aspect of the present invention: the first threshold is 56 kg, the second threshold is 28 kg, the first quantity is 3, the second quantity is 2, and the third quantity is 1.

[0016] As a further aspect of the present invention: the execution mapping algorithm generates a parameterized sequence of process steps, specifically including: Parse the user-input sequence of process steps and identify the material action entries within it; Count the number of times the same material action occurs in the sequence of process steps; Based on the number of occurrences, extract the weight values ​​corresponding to the number of occurrences from the preset weight parameter list corresponding to the material in the bill of materials data in sequence; The extracted weight values ​​are associated with the corresponding material actions to generate weighted process steps.

[0017] As a further aspect of the present invention: when the material action corresponds to a split material bag, if the material action corresponding to the material bag appears once in the process step sequence, then the total weight of the material bag multiplied by the number of material bags is used as the associated weight value.

[0018] The second aspect of the technical solution: A design system employing a Teamcenter-based visual design method for tire formulation application as described in any of the above-mentioned aspects, comprising: The data acquisition module is used to receive construction design instructions for the formula object and to acquire bill of materials data and manufacturing resource data from the product lifecycle management system. The bag splitting module is used to identify the fine materials that need to be split based on the bill of materials data, and generate a bag splitting scheme according to equipment capacity constraints and preset rules. The semi-finished product generation module is used to respond to the user's editing operation on the material bag splitting scheme, update the splitting scheme, and generate a semi-finished product object associated with the fine material; The process design module is used to dynamically generate a process configuration interface corresponding to the machine tool based on the manufacturing resource data, and to execute a mapping algorithm to generate a sequence of process steps with parameters in response to the user's input of the process and parameters. The data association module is used to associate the process step sequence with the semi-finished product object to generate a construction standard object, and to establish a versioned association between the construction standard object and the formula object.

[0019] Compared with the prior art, the present invention has the following technical advantages: This invention automates material usage calculation and enables real-time compliance verification by automatically identifying fine materials based on classification attributes, adaptively calculating the number of material bags driven by weight thresholds, and allocating materials according to machine matching degree. Its advantages include: eliminating errors introduced by manual calculations, automatically adapting the material bag splitting results to equipment physical constraints, ensuring the calculation process is traceable and reusable, and significantly improving the reliability of formulation and construction design.

[0020] By employing a graphical process design interface, adaptive pagination of machine topology, a motion-weight dynamic mapping algorithm, and semantic verification of control parameters, deep coupling between process logic and material parameters is achieved. The benefits include: intuitively expressing process logic relationships through node-connection methods; supporting linked parameter updates and automatic alerts for logical conflicts; significantly improving the efficiency and accuracy of process design; and facilitating more convenient iterative optimization of process solutions.

[0021] By constructing a three-level association structure of detailed materials, semi-finished products, and construction standards, along with a version upgrade strategy and an automatic construction data collection mechanism, the formulation and construction design business is deeply embedded into the product lifecycle management system workflow. Its benefits include: eliminating the disconnect between design tools and the data management platform; achieving automatic synchronization and full traceability of design and manufacturing data; and ensuring data consistency throughout the product lifecycle.

[0022] Through a two-level parameter data source inheritance mechanism, new formulas can automatically inherit the enterprise's standard process parameters while retaining the customized parameters of specific formulas. This balances the standardization and flexibility of process management and reduces the configuration cost of formula construction design. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please refer to Figure 1 In this embodiment of the invention, a visualization design method for tire formulation application based on Teamcenter includes the following steps: Step S1: Receive construction design instructions for the formulation object, and obtain bill of materials data and manufacturing resource data from the product lifecycle management system; In this embodiment, the user logs into the system through the Teamcenter client, selects a created tread compound formulation construction standard version object in the formulation management module, and selects "Start Formulation Construction Design Tool" via the right-click menu. In response to this construction design instruction, the system retrieves the Bill of Materials (BOM) data and manufacturing resource data associated with the formulation object from the Teamcenter database.

[0033] Step S2: Identify the sub-materials that need to be split based on the bill of materials data, and generate a material bag splitting scheme according to equipment capacity constraints and preset rules; Specifically, based on the material classification attributes in the bill of materials data, the set of sub-materials that need to be split into bags is identified, and according to the equipment capacity constraints and preset weight threshold rules defined in the manufacturing resource data, a visual bag splitting interface containing the number of bags and the material allocation scheme in each bag is generated. The weight threshold rules define the dynamic correspondence between the total weight of the bags and the number of bags. Step S3: In response to the user's editing of the material bag splitting scheme, update the splitting scheme and generate semi-finished product objects of the associated fine materials; Specifically, in response to the user's editing operation on the visual bag splitting interface, the bag allocation scheme is updated, and based on the updated bag allocation scheme, at least one semi-finished product object is created in the product lifecycle management system. The semi-finished product object is associated with the materials in the detailed material set through the bill of materials structure. Step S4: Dynamically generate a process configuration interface corresponding to the machine based on the manufacturing resource data, and execute a mapping algorithm to generate a sequence of process steps with parameters in response to the user's input of the process and parameters. Specifically, a graphical process design interface is provided. The interface dynamically generates a process configuration area corresponding to the machine based on the machine topology information in the manufacturing resource data. In response to the user's input of process nodes and process parameters in the process configuration area, an action-weight mapping algorithm is executed to dynamically associate the number of times material actions occur in the process steps with multiple weight parameters in the bill of materials data, and semantic verification of control parameters is performed to generate a structured sequence of parameterized process steps. Step S5: Associate the process step sequence with the semi-finished product object to generate a construction standard object, and establish a versioned association with the formula object.

[0034] Specifically, the parameterized process step sequence is associated with the semi-finished product object to generate a construction standard object, and the construction standard object and the formula object are linked in a versioned manner in the product lifecycle management system.

[0035] In this embodiment, the step of identifying the sub-materials that need to be split based on the bill of materials data specifically includes: Iterate through the material entries in the bill of materials data, obtain the classification attribute associated with each material entry, and when the weighing method attribute value in the classification attribute matches the preset fine material scale identifier, classify the material entry into the fine material set.

[0036] In this embodiment, the step of generating a bag splitting scheme based on equipment capacity constraints and preset rules specifically includes: Obtain the total weight of each material in the fine material set; The total weight is compared with at least one weight threshold. When the total weight is greater than or equal to the first threshold, the number of material bags is determined to be the first quantity; When the total weight is less than the first threshold and greater than or equal to the second threshold, the number of material bags is determined to be the second number; When the total weight is less than the second threshold, the number of bags is determined to be the third number; The total weight is evenly distributed among the bags based on the determined number of bags.

[0037] In this embodiment, the bag splitting scheme further includes: Based on the compatibility relationship between each batching machine and the processable materials defined in the manufacturing resource data, the matching degree between the materials in the fine material set and each batching machine is calculated. The batching machines are sorted according to the matching degree, and the materials in the fine material set are automatically allocated to the material bags associated with the corresponding machines according to the sorting priority. Materials not assigned to any batching machine are placed in the semi-automatic weighing area.

[0038] In this embodiment, the generation of the semi-finished product object of the associated fine material specifically includes: Create a semi-finished object for each split bag; In the bill of materials structure of the semi-finished product object, add material entries belonging to the bag, and set the usage, weight and bag serial number attributes for each material entry.

[0039] This embodiment also includes: After updating the bag splitting scheme in response to a user's editing operation, the consistency of the bag splitting scheme before and after the update is verified. Version upgrade operations are performed on the corresponding semi-finished objects only when the content consistency verification result is changed.

[0040] In this embodiment, the first threshold is 56kg, the second threshold is 28kg, the first quantity is 3, the second quantity is 2, and the third quantity is 1.

[0041] In this embodiment, the execution of the mapping algorithm to generate a parameterized sequence of process steps specifically includes: Parse the user-input sequence of process steps and identify the material action entries within it; Count the number of times the same material action occurs in the sequence of process steps; Based on the number of occurrences, extract the weight values ​​corresponding to the number of occurrences from the preset weight parameter list corresponding to the material in the bill of materials data in sequence; The extracted weight values ​​are associated with the corresponding material actions to generate weighted process steps.

[0042] In this embodiment, when the material action corresponds to a split bag, if the material action corresponding to the bag appears once in the process step sequence, the total weight of the bag multiplied by the number of bags is used as the associated weight value.

[0043] In this embodiment, the product lifecycle management system is the Teamcenter system, and the formula is a tire rubber compound formula.

[0044] like Figure 2 and Figure 3 As shown, the diagram illustrates the visual interface and core algorithm flowchart for the step of splitting the material bag.

[0045] The interface provides a parameter input area at the top. Users input a fill factor of 1.2 and a weight factor of 0.9, then click the "Calculation Preview" button. The system then performs the following automated recognition and calculation process: (1) Automatic identification of fine materials: The system recursively traverses all material entries in the AllocCompound BOM view and obtains the classification attribute associated with each material entry. When the weighing method attribute value in the classification attribute matches the preset fine material scale identifier, the material entry is classified into the fine material set. In this embodiment, the weighing method of 8 materials, including accelerator CZ, accelerator DM, and antioxidant 4020, is "fine material scale", and they are automatically identified as fine materials that need to be separated.

[0046] (2) Total Weight Calculation and Bag Quantity Determination: The system calculates the total weight of each material in the fine aggregate. In this embodiment, after adjusting the filling coefficient and weight coefficient, the total weight of the fine aggregate is 42.5 kg. The system compares the total weight with at least one weight threshold. Specifically, the first threshold is set to 56 kg, and the second threshold is set to 28 kg. Since 42.5 kg is less than the first threshold of 56 kg and greater than or equal to the second threshold of 28 kg, the system determines the bag quantity to be the second quantity, i.e., 2 bags. The system distributes the total weight equally among the bags according to the determined bag quantity, with each bag weighing 21.25 kg.

[0047] (3) Intelligent matching of machines and materials: Based on the compatibility relationship between each batching machine and the materials that can be processed as defined in the manufacturing resource data, the system calculates the matching degree between the materials in the fine material set and each batching machine. Specifically, the system obtains the list of materials that can be processed by each batching machine through the Teamcenter query interface Giti_Find_MatchingMaterialMachine. For the 8 materials in the fine material set, the system calculates the number of intersections with machine A (best machine) and machine B (second-class machine) as the matching degree. The system sorts the batching machines according to the matching degree and automatically assigns the materials in the fine material set to the material bags associated with the corresponding machines according to the sorting priority. In this embodiment, 5 materials are matched to the automatic weighing material bag corresponding to machine A, 2 materials are matched to machine B, and the remaining 1 material that is not assigned to any batching machine is assigned to the semi-automatic weighing area.

[0048] The calculation results are presented in the interface as a list of material bags. Users can manually adjust the number of material bags using the "Add Material Bag" or "Remove Material Bag" buttons, or drag and drop material items between material bags to adjust the allocation scheme. The same material name can be selected from different material bags using mutually exclusive button groups (ButtonGroup), ensuring that the same material is allocated to only a single material bag.

[0049] After the user confirms the bag allocation plan, they click the "Save" button. The system then performs the following persistence operations: (4) Semi-finished product object creation: The system creates a semi-finished product object (SemiComptRevision type) for each split material bag. In the bill of materials (AllocCompound) structure of the semi-finished product object, material entries belonging to that material bag are added, and the usage, weight, and material bag serial number attributes are set for each material entry. Specifically, the material bag serial number (e.g., "1 / 2", "2 / 2") is stored through the PackageCode attribute. This step corresponds to the technical solution described in claim 5.

[0050] (5) Update the original construction standard BOM: In the AllocCompound BOM of the original formula construction standard object, the original fine material entries are replaced with references to the corresponding fine semi-finished products objects, and the quantity of material bags is stored in the relation attributes.

[0051] (6) BOP process list update: The system inserts a batching construction standard object into the process list. This object is associated with the above-mentioned fine material semi-finished products and represents the batching process.

[0052] (7) Version Upgrade Control: After the system responds to the user's editing operation to update the bag splitting scheme, it performs a content consistency check on the bag splitting scheme before and after the update. Only when the content consistency check result is a change will the corresponding semi-finished product object be upgraded. If the check result is no change, the original version will remain unchanged.

[0053] (8) Construction data collection: The above-generated fine material semi-finished product objects and batching construction standard objects are automatically collected into the "Construction Data" folder under the formula component to achieve unified management.

[0054] like Figure 4 As shown, the diagram illustrates a visual interface for the design process steps. like Figure 5 As shown in the figure, the diagram is a schematic diagram of the pop-up window of the process step selection interface that appears when the button is pressed. like Figure 6 As shown, the diagram is a flowchart of the core algorithm for each step of the design process. Based on the manufacturing resource data, the system dynamically generates a process configuration interface corresponding to the machine. Specifically, the system automatically identifies the internal mixer topology by acquiring the internal mixer resources associated with the construction standard object. In this embodiment, the system creates a tab containing a process step design table, a material information table, and a process step text display area.

[0055] Users click the "Add" button to add a row to the process step design table. Each row contains the following editing elements: a "Full Name of Action" column, which users can access via the "Please Select" button. Figure 4 The process step selection interface shown allows users to select one or more actions from a preset action library. In this embodiment, the user selects actions such as "raw rubber plasticizing", "carbon black addition", "fine material addition", "oil addition", and "plastic discharge". In the "control method" column, the user selects options such as "time control" or "temperature control". In the "time / temperature" column, the user enters specific control parameter values, such as plasticizing time of 180 seconds and plastic discharge temperature of 145℃.

[0056] The material information table at the bottom of the interface automatically loads materials from the construction BOM, including the fine semi-finished products generated after step one. For fine semi-finished products, the system automatically displays the number of associated material bags. Users can enter multiple weight parameters for each material in this table: primary weight, secondary weight, tertiary weight, and quaternary weight, to support multiple applications of materials during the process.

[0057] After the user completes the editing, they click the "Convert Process Steps" button. The system executes a mapping algorithm to generate a parameterized sequence of process steps, specifically including: (1) Parse the process step sequence input by the user and identify the material action entries. Taking accelerator CZ as an example, this material appears twice in the process step sequence (once in the master refining section and once in the final refining section).

[0058] (2) Count the number of times the same material action appears in the process step sequence.

[0059] (3) Based on the number of occurrences, extract the weight values ​​corresponding to the material from the preset weight parameter list in the bill of materials data. For accelerator CZ, the system extracts the first two weight values ​​from the material information table in sequence: the first weight is 1.2 kg, and the second weight is 0.8 kg.

[0060] (4) Associate the extracted weight value with the corresponding material action to generate a process action with weight, such as “accelerator CZ_1.2Kg” and “accelerator CZ_0.8Kg”.

[0061] When executing the above mapping algorithm, for the fine material semi-finished product generated by step one, if the material action corresponding to the bag appears only once in the process step sequence, then the total weight of the bag multiplied by the number of bags is used as the associated weight value. In this embodiment, the total weight of the fine material semi-finished product is 21.25 kg, the number of bags is 2, the appearance frequency is 1, and the associated weight value is 42.5 kg, indicating that all two bags of fine material are added at once.

[0062] Simultaneously, the system performs semantic verification on the control parameters: it reads the control methods and parameter rules defined in the configuration file; when the control method is "time control," it verifies whether the time parameter has been entered; when the control method is "temperature control," it verifies whether the temperature parameter has been entered. After successful verification, the control parameters are appended to the end of the process steps to form a complete process step text, such as "Raw rubber plasticizing → Time control_180s → Carbon black addition_35.2Kg → Accelerator CZ_1.2Kg → ... → Glue discharge → Temperature control_145℃".

[0063] The generated complete process step sequence is displayed in the text area at the bottom of the interface, and the system stores the sequence in the process data array of the corresponding machine.

[0064] like Figure 7 As shown, the diagram illustrates a visual interface for setting process parameters.

[0065] like Figure 8 As shown, the diagram illustrates the core algorithm flowchart for setting process parameters.

[0066] The system generates a parameter configuration interface based on the internal mixer topology. For a single-machine scenario, each page contains four parameter configuration tables: TCU setting table, constant temperature parameter table, boundary parameter table, and auxiliary machine setting table.

[0067] The parameter loading adopts a two-level data source mechanism: The system first checks whether the machine process form corresponding to the formula exists. If it exists and there is data at the corresponding array index position of the machine, the customized parameter is loaded first; if it does not exist or the data at that position is empty, the system concatenates the process parameter standard object ID by the internal mixer model and the sheeting method, queries the latest issued object, and reads the default parameter value in the category attribute as the initial value.

[0068] Users fill in or modify parameter values ​​in various tables. For example, in the TCU settings table, the host computer sets the temperature to 45℃ and the slave computer sets the temperature to 40℃; in the constant temperature parameter table, the target temperature is 145℃ and the holding time is 120 seconds; in the boundary parameter table, the highest temperature alarm value is 160℃ and the lowest temperature alarm value is 130℃; in the auxiliary machine settings table, the open mill roll gap is 5mm and the roll speed is 30rpm.

[0069] After the user clicks the "Save" button, the system stores the data from each table into the array attribute of the form object according to the machine ID correspondence. At the same time, the system synchronizes the first row of process step text of the first machine to the category attribute of the construction standard object, and synchronizes the first row of speed value to the attribute so that the downstream MES system can read it directly.

[0070] The second aspect of the technical solution: A design system employing a Teamcenter-based visual design method for tire formulation application as described in any of the above-mentioned aspects, comprising: The data acquisition module is used to receive construction design instructions for the formula object and to acquire bill of materials data and manufacturing resource data from the product lifecycle management system. The bag splitting module is used to identify the fine materials that need to be split based on the bill of materials data, and generate a bag splitting scheme according to equipment capacity constraints and preset rules. The semi-finished product generation module is used to respond to the user's editing operation on the material bag splitting scheme, update the splitting scheme, and generate a semi-finished product object associated with the fine material; The process design module is used to dynamically generate a process configuration interface corresponding to the machine tool based on the manufacturing resource data, and to execute a mapping algorithm to generate a sequence of process steps with parameters in response to the user's input of the process and parameters. The data association module is used to associate the process step sequence with the semi-finished product object to generate a construction standard object, and to establish a versioned association between the construction standard object and the formula object.

[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention. The scope of the invention is defined by the appended claims and their equivalents, all of which should be included within the scope of protection of the invention.
